How long will a solution of NyGuard IGR and water last ?
We recommend only mixing NyGuard IGR when you are ready to treat and mix only what is needed. Once it has been mixed with water, the solution must be used or discarded within 24 hours. Before mixing, the shelf lilfe is 3-5 years from the date of purchase if stored at room temperature.
